Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster
L. Izzo, C. Gall, N. Khetan +47
Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…
SN 2021foa: The "Flip-Flop" Type IIn / Ibn supernova

We present a comprehensive analysis of the photometric and spectroscopic evolution of SN~2021foa, unique among the class of transitional supernovae for repeatedly changing its spec…
Double "acct": a distinct double-peaked supernova matching pulsational pair-instability models
C. R. Angus, S. E. Woosley, R. J. Foley +35
We present multi-wavelength data of SN2020acct, a double-peaked stripped-envelope supernova (SN) in NGC2981 at ~150 Mpc. The two peaks are temporally distinct, with maxima separate…
SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS
Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28
The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
Flight of the Bumblebee: the Early Excess Flux of Type Ia Supernova 2023bee revealed by , and Young Supernova Experiment Observations
Qinan Wang, Armin Rest, Georgios Dimitriadis +41
We present high-cadence ultraviolet through near-infrared observations of the Type Ia supernova (SN Ia) 2023bee in NGC~2708 ( Mpc), finding excess flux in the first d…
The restframe ultraviolet of superluminous supernovae -- I. Potential as cosmological probes
Nandita Khetan, Jeff Cooke, Marica Branchesi
Superluminous supernovae (SLSNe) have been detected to and can be detected to using current and upcoming facilities. SLSNe are extremely UV luminous, and henc…
SN 2022ann: A type Icn supernova from a dwarf galaxy that reveals helium in its circumstellar environment
K. W. Davis, K. Taggart, S. Tinyanont +64
We present optical and near-infrared (NIR) observations of the Type Icn supernova (SN Icn) 2022ann, the fifth member of its newly identified class of SNe. Its early optical spectra…
The Young Supernova Experiment Data Release 1 (YSE DR1): Light Curves and Photometric Classification of 1975 Supernovae
P. D. Aleo, K. Malanchev, S. Sharief +80
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multi-color Pan-STARRS1 (PS1) griz and Zwicky Transient Facility (ZTF) gr photometry of 1…
Virgo Detector Characterization and Data Quality: tools
F. Acernese, M. Agathos, A. Ain +491
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the jo…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
A fast rising tidal disruption event from a candidate intermediate mass black hole
C. R. Angus, V. F. Baldassare, B. Mockler +36
Massive black holes (BHs) at the centres of massive galaxies are ubiquitous. The population of BHs within dwarf galaxies, on the other hand, is evasive. Dwarf galaxies are thought…
Virgo Detector Characterization and Data Quality during the O3 run
